ANALYSIS OF THE CHARACTERISTICS OF WINTER GALES NEAR THE SOUTH GEORGIA ISLANDS IN 2016
摘要
Abstract
The weather at the South Georgia Islands is frequently windy and the general weather situation is complex. Based on surface weather charts and observations from a fishing ship, we concluded that the synoptic situations that lead to winter gales near the South Georgia Islands could be divided into three types: (1) a single cyclone, (2) high pressure to the north and low pressure to the south, and (3) high pressure to the west and low pressure to the east. Type 1 causes gales with moderately short durations. Type 2 causes gales with the longest durations. Type 3 is often generated by an eastward shift of the saddle-shaped pressure system, producing gales with the shortest durations. However, Type 3 can produce wind waves in directions different to the climatological mean direction, which potentially could be dangerous for fishing ships and therefore, careful monitoring is required.关键词
